Installation Notes

Installation Precautions

•  Do not use the reducer/gearmotor for specifications 

other than those shown on the nameplate or in the 
manufacturing specification documents  Personnel 
injury and/or equipment damage may occur 

•  Do not place combustible material on or around 

the unit; fire may occur 

•  Do not place any objects around the unit that will 

prohibit proper ventilation  Inadequate ventilation 
may lead to high unit temperature and/or fire 

•  Do not step on or hang from the unit. Excessive 

weight may cause component breakage leading to 
personnel injury and/or equipment damage 

•  Do not touch the shaft, keyway, or motor fan with 

bare hands; injury may occur 

•  For applications in which lubricant leaks could 

adversely affect operations (i.e., package handling, 
food processing), place an oil pan below the unit to 
protect against contamination that may occur if oil 
seals become damaged or worn 

Installation Location

Ambient Temperature Range:  14 – 104°F (-10 – 40°C)
Ambient Humidity:  85% or less
Altitude:  3,280 feet (1,000 m) or less
Atmosphere: The location should not contain corrosive gas, 
explosive gas, or steam  The location should be free of dust and 
well ventilated 
Location: Indoor – free of dust and water

Consult Sumitomo when the unit will operate in conditions other 
than those specified above   Special unit modifications may be 
required 

Units manufactured according to customer specified application 
requirements (i e  outdoor modifications, high-temperature 
modifications) are designed to operate within the specified 
environment 

Install the unit so inspection and/or maintenance procedures may 
be easily performed  Install all units that are not shaft mounted 
on a sufficiently rigid base 

Installation Angle

You must mount the unit horizontally 

 Please consult Sumi-

tomo if the unit needs to be installed in a position other than 
horizontal 

If the unit was manufactured for a mounting position other than 
horizontal, 

do not mount it in a position other than the one 

specified 

Horizontal is the shaft orientation for standard units  Consult 
Sumitomo for shaft directions other than horizontal 

•  Do not remove the eye-bolt from the motor. Should 

you need to remove the eye-bolt for any reason, 
install a replacement bolt in the tapped hole to 
prevent water from entering the motor 

Severe Loading Conditions

For applications with severe vibration and/or frequent starts and 
stops, Sumitomo recommends the use of high-strength bolts of 
Grade 8 8 (or greater) to mount the reducer/gearmotor 

Installation onto the Driven Machine

•  Before mounting the reducer/gearmotor to the 

machine, verify the appropriate/desired rotation of 
the machine  Differences in the rotational direc-
tion may cause personnel injury and/or equipment 
damage 

•  If a key is attached to the keyed hollow bore, tem-

porarily remove the key if the unit is not coupled to 
the driven machine and you wish to run the unit 

•  Before operating the unit, ensure that all safety 

guards around the rotating components are 
in-place and secure  Failure to do so may result in 
personnel injury 

•  When joining the reducer or gearmotor to the load, 

ensure that the center alignment, belt tension, and/
or parallelism of the coupling device are within the 
coupling manufacturer’s established recommenda-
tions  For applications with a belt, ensure that the 
belt is properly tensioned to the manufacturer’s 
specification, and the bolts securing the pulley 
and couplings are sufficiently tightened  Failure to 
follow these precautions may result in personnel 
injury and/or equipment damage
